I just tried this, excellent UI. I was (am) currently using File Expert (very happy with it), but this looks much better. Have not been able to connect to my PC yet (but haven't tried too hard).
Also, File Expert has a "Favorites" which is real nice for most used folders.
Also, when I "Sort" by date, it sorts from oldest to newest, needs to go from newest to oldest (so newest is at top), doesn't appear to have that option. Will try this for a few days.
1. Connected to PC, had my Username wrong.
2. Still need to sort by decending date.
3. I can only copy 1 file to the clipboard, should be able to copy multiple.
4. Don't think I need a "Favorites" with the categories you have, but it would be nice (and necessary if you don't fix the sort issue).
5. Need a way to EXIT the app. Can't use Back, and there's no exit button. Have to hit Home and kill the app with a killer of some sort (I use GO Launcher).
